There have been lot of changes recently in the test pattern. A few schools shifted from GL assessment to CEM pattern. A few schools shifted the pattern from one test to two stage tests. CEM exams were developed by the Centre for Evaluation & Monitoring at the University of Durham. CEM exams were introduced in response to fears that existing 11 Plus exams had become too transparent. CEM do not publish practice materials and change the format of examinations every year.

CEM exams consist of two 45-minute papers. A short break is normally given between the two papers. Each paper has a mix of topics covering English, verbal reasoning, non-verbal reasoning and maths (numerical reasoning). The papers are spilt into sections, with varying numbers of questions and timings. Often more questions are provided than are likely to be answered. Children are only given a set amount of time to answer a section and cannot move forward until told to proceed.
